PEDIGREE. 
The Pedigree of a plant must be known in scientific propagation oecause it requires several years 
to breed up and develop it, and the line of ancestry must not he broken by propagating from any weak 
plant 
A THOROUQHBRED PLANT. 
A Thoroughbred plant is one possessing the best characteristics of its variety, the result of grow- 
ing them continuously under the most favorable environments and accumulating good qualities through 
annually selecting the desirable variations and discarding weaklings and restricting to prevent pollen and 
seed exhaustion, thus preserving a perfect balance between vegetative parts and its fruit-producing 
organism. 
THE PEDIGREE OF THESE PLANTS. 
The pedigree of each plant offered in this catalog, unless otherwise stated in the description, shows 
the ancestsy in lineal ascent to have been thoroughbred as above stated, and they are believed to be per- 
fect in their physical and fruiting organism in all respects. 
nONGREL PLANTS. 
Mongrel plants are those grown under ordinary conditions, without any systematic selection of 
bud variations, and for the want of proper restriction are more or less pollen exhausted and therefore 
have a strong tendency to make runners rather than strong fruit buds. They do not give uniformity or 
quality to fruit under any system of tillage that can be used. 
THE CAUSE AND EFFECT. 
I have pointed out the cause of unfruitfulness in plants and given the effectual remedy as proven 
by repeated definite experiments which may be summed up as follows : 
The most congenial environments to induce better variations and continuously selecting those 
making the greatest improvement and keeping them under restricted fruitage to develop their fruit pro- 
ducing organism. These methods have met the warmest approval of the highest horticultur.nl experts in 
the country, and especially that of the International Conference of Plant Breeders. I have been the pioneer 
in this work and have the only establishment in the country having perfect conditions for plant breeding. 
STOCK FOR PROPAGATION, 
We make a specialty of furnishing fruit growers with Thoroughbred Plants for their jjropagating 
beds from which they can grow perfect plants which are able to respond to high culture with larj^e ber- 
ries and plenty of them as well as for general planting. 
THE DEHAND. 
Up to this time the demand has been beyond our ability to supply. Wherever they have been 
seen in fruit under good cultivation they have created a sensation, and in order to meet this demand I 
have discontinued propagating all other plants and this year offer a stock several times greater and much 
finer than e\ er before, but indications are that the rush for them w'U be equally great and so orders 
must be filled in the rotation received. Orders should therefore be booked as early a? possible. Our 
customers are always leaders on the markets. 
THE PHOTOGRAPHS. 
Typical specimens of each variety were photographed in the season of 1902 an<l engraved to show 
the size and form of the berries of different varieties, but the camera cainiot do them justice as the beau- 
tiful color, delicious flavor and firm texture cannot be put in the picture. 
The seeming uniformity of berries of different varieties arises out of continued sejectiojl jf those 
approaching the most nearly to the idea' type. It is the result of skilful propagation through a ;ries of 
years. 
Copies of this book will be sent free to any four of your friends with you- name and complin. 
■written on each book so they will know that you .sent it. Send in their names. They must be persons 
interested in berry growing.
